What is the official name of the SLC3A1 gene?
The official name of this gene is “solute carrier family 3 (cystine, dibasic and neutral amino acid transporters, activator of cystine, dibasic and neutral amino acid transport), member 1.”
SLC3A1 is the gene's official symbol. The SLC3A1 gene is also known by other names, listed below.

What is the normal function of the SLC3A1 gene?
The SLC3A1 gene provides instructions for producing one part (subunit) of a protein made primarily in the kidneys. This subunit joins with another protein subunit, produced from the SLC7A9 gene, to form a transporter protein complex. During the process of urine formation in the kidneys, this protein complex absorbs particular protein building blocks (amino acids) back into the blood. In particular, the amino acids cystine, ornithine, arginine, and lysine are absorbed back into the blood through this mechanism.
Does the SLC3A1 gene share characteristics with other genes?
The SLC3A1 gene belongs to a family of genes called SLC (solute carriers).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
